IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 156,661, dated November l0, v1874; application filed April 29, 1874.

To all whom it may concern:

Be it known that I, LEWIS S. DANIELs of Foxborough, in the county of Norfolk, in the State of Massachusetts, have invented a certain new and useful Improvement in Pumps,

H the valve-stem, made as shown. The brake B has a ball, O, upon it. This ball O fits into 'a semi-spiral seat, D D, made in the barrel A. E is a cap or follower, formed to fit the ball O,

and also the recess in D D, and thus constitute a packing-box for the ball C. F represents a space to be filled With some suitable packing material. The cap or follower E may be fastened in any suitable manner to the barrel A.

By this arrangement it may be seen that I have a very simple, Cheap, and self-adjusting Water-tight joint between the brake and pumpbarrel. In force-pumps the upper part of the barrel forms an air-chamber for the pump.

I claim as my inventionv The combination of the brake B and ballA and-socket joint O E D D with the pumpbarrel A, substantially as described, and for the purpose set forth.
